no thanks

Why not?

Why does that code exist anyway? It at least needs a comment.

OK, whatever.

If test fails, it better record buggy output somewhere (to coredump or to terminal).

+1 on reporting results - the best way to do this is to add a meaningful message
for users to understand what went wrong.

Please suggest how you would like this warning addressed and report the error.
